It retrieves the latest PR metadata via GitHub API and parses the body +as JSON. It never executes reported test commands or PR source with secrets. +The `T27 work report` status is written to the PR's **head SHA**, not the base +commit. Opening, editing, synchronizing or reopening a PR regenerates the draft. + +The workflow stores `report.json`, `post.json` and a readable `draft.md` as an +artifact. A generated `post.json` remains `published:false`: this is real draft +content, not a claim that an article or illustration is live. + +Only merged PRs get a durable, PR-number-keyed blog publication issue. Retries +reuse the issue, including after 24 hours; event deduplication alone is not a +durable ledger. Closed-unmerged PRs never enter the publication queue. A failed +dispatch fails visibly and keeps the draft/task recoverable. Re-run the workflow +with its PR number after resolving a failure. + +The exact PR/outbox numbers are sent to `pr-blog-author.yml` by explicit GitHub +workflow dispatch. This uses the repository's existing Claude Code OAuth runtime +and `AGENT_GH_TOKEN` for publication PRs (no repository-wide PR approval setting +is enabled); +missing/expired authorization is a visible failure, never a fake publication. +It does not use the generic Inngest skill event: the inspected consumer ignored +PR payloads and its Queen worker watched `gHashTag/t27`, not this repository. +The daily Inngest schedule and other repositories are left unchanged. + +After an acknowledged author dispatch that later fails, rerun the **author** +workflow with the same PR/outbox numbers. The report workflow will not blindly +redispatch an already acknowledged task. The author's per-PR concurrency and +source-receipt search prevent duplicate article creation on a deliberate retry. +GitHub-token-created PRs need explicit report and website CI workflow dispatches; +ordinary PR events may be suppressed by GitHub's recursion protection. + +The publication worker must read the exact source PR, merge commit, work report, +diff and CI. It writes a useful article through `.claude/skills/blog-post/SKILL.md` +in the existing `apps/website/src/data/blog/` schema, with receipts, +`openQuestions`, complete body, meaningful tags and a relevant existing service +offer. EN/RU versions must preserve the same factual limits. No title-only posts. + +Use the intact 1200 × 630 engraved three-panel img2img artwork with the established +references. Honor GPT Image 2 preference; never invent a model ID the runtime +does not expose. If generation is unavailable, keep the draft/task pending: +do not substitute a generic title card or silently ship without a picture. + +Before creating an article, find an existing article by **source PR receipt and +topic**, not just slug. If the PR already publishes a blog article, its outcome +is that article: verify it and link it, without recursively creating a new +article/PR about publishing an article. Close the publication task only after +the canonical live article, body, image, hashtags and offer are verified. + +Social promotion belongs to the existing paced queue, not one instant blast per +PR: X `@t27_dev`, personal LinkedIn `neurocoder`, Telegram `@t27_lang` only. Use +English X/LinkedIn and Russian Telegram when translated; one X hashtag and two +or three LinkedIn/Telegram hashtags, derived from article tags. Deduplicate +published and scheduled topics and use the complete triptych with ALT. + +## Required merge gate + +The repository setting must require `T27 work report` from GitHub Actions on +`main`. Merely adding YAML or this document does not enforce merging. Configure +the rule only after the workflow is installed and its real status has been +observed.
